  • Verify that the speed sensor is correctly aligned with the wheel magnet and securely attached to the fork.
  • Check the wheel circumference setting in the unit's configuration menu. An incorrect setting will lead to inaccurate readings.
  • Ensure there are no obstructions or strong electromagnetic interference near the sensor or main unit.
• Display Not Responding to Touch:
  • Ensure the display surface is clean and free of dirt or moisture.
